我用的球衣+休眠和具有这种errror编写RESTful Web服务一个Java Maven项目：休眠+的PostgreSQL抛出一个异常：JDBC驱动程序类未找到：org.postgresql.Drive

这应该是'org.postgresql添加缺少的r。** **驾驶员'不是'Drive' – fge

这个代码是否与这个问题有关？请仅包含[必需的最小代码量]（http://stackoverflow.com/help/mcve）来复制问题。 – IronFlare

添加PostgreSQL的行家依赖于你的POM文件

<dependency> 
    <groupId>postgresql</groupId> 
    <artifactId>postgresql</artifactId> 
    <version>9.1-901-1.jdbc4</version> 
</dependency>

和驱动

<property name="connection.driver_class">org.postgresql.Driver</property>

谢谢@Reimeus这个工程........ :) – Asad

@fge其org.postgresql.Drive没有驱动程序...... – Asad

@IronFlare感谢建议，我将在未来大约需要照顾它,,, ,,,, – Asad
